miniport: disable surfaces by default
Change the registry checking logic we already have, instead of enabling
surfaces by default we now disable surfaces by default. They can be
enabled without driver change by creating a registry key name
"SurfacesEnabled" of type DWORD with any value under the adapter key.
To find the adapter key, one way is looking for the key under which
there is a value of name "QxlDeviceID" after a successfull startup of
the qxl driver.
